Using high-analysis fertilizers lacking adventitious sulfur (S), coupled with traditional cropping-systems that mine S from native soil, leads to S deficiency. However, under field conditions, S deficiency symptoms are not easily identifiable in cereals, because they are mistaken...

Six on-farm experiments were conducted in 2013/2014 seasons, in the Central Highlands (CHLs) of Ethiopia, with the main aim of estimating optimum sulfur rate for wheat. The treatments were, 4-levels of S(S0 =0, S1 =5, S2 =10, and S3 =20 kg S/ha); 2-levels of N(N0 =0, N =N1 =69 kg...
